Divided and this application filed February 17, '1930.

My invention has reference to :a press-for` automobile: axles, `of Ya class set forth in' my former application for Letters .Patent of; theUnite'd 'States Vtiled December 21st, 1928,

Serial No."327,643, out -ofwhich the present application is divided. One of the fundamental features of the invention set forth in said former application -was a pit or opening in the floor of suliicient depth for mechanics to work in, and a cross-beam rigidly secured in the side walls of the pitY near the top thereof. The original invention had for its purpose to provide for the straightening of an axle in a vertical plane,

f; whereas the present invention is more specially designed for assisting in taking the twist out of an axle. The invention is adaptable for use with a cross-beam of the character set forth in said former application, but is not limited to such use. It comprises one of several sets of tools by which various faults in an axle may be treated, and corrected.

The particular construction, arrangement i and operation of the various parts of the invention will be more fully understood from the following specilication, reference being had to the accompanying drawings, in which;-

Fig. l is a plan view showing the machine in position for taking the twist out of an axle.

Fig. 2 is a cross-section on the line 2 2 of Fig. l.

F ig. 3 is a detail of the Wedge 2l, in perspective.

Fig. 4 is a crosssection of an axle with a modified form of clamp applied thereto.

Fig. 5 shows one of1 the clamp-plates onA the line 5-5 of Fig. 4.

Fig. 6 is a detail in section of the bar 18 and appui-tenant parts.

The invention is shown in Figures l and 2 oi the drawings, in which the reference a building,

A1 bearing ion `the pin Lis .falorded for the outer end :of thefzbarby means VVKofsa wedge 2l providedwith a series ofsstepped bear` ings 22, with one ofi which2the1pin1r20 .is-ieu gaged. /Supportedvonthe cross-beam 5 5` isa` power-jack 23, the 'rod 2416i? which bears againstfthe projectingend of the bar L18.

The force'of the ljack tends; to raisexthe inner-end of thebar l8:-and"lowerfthe.` outer end, #which-outer-end zis. at the same f time guided an'd Vheld' vdownwardly by the operator, by means offra;:pipefextension on the end offsaidg-bar. By this r'meansithe'endyof the axle can be bent back intoia'itrue `position, .and the forcecanialso` be imparted .to intermediate parts Y-ojf the axleV to "makezcorrectionstherein.

@In Figures l4feand l 5. a somewhat. .similar device is Ashown "which" can be employed 'in straightening theV axle 27, -when there .isa twist therein, in which the `axle Ais .supported in its 'normal position, and uis securedyto the clamp-plate l0 in any suitable mannerazone -such --means being set `forth in` my "compan- At the sides of the axle are clamp-plates 28 and 29, united at their corners by bolts 30, held in place by nuts 31. A pair of blocks 32 and 33 have a trunnion connection with the plates 28 and 29, respectively, as at a and permitting said blocks to turn independently of the plates. The inner faces of the blocks conform in shape to the flanges of the axle. The plate 28 is fitted with a bar 34, having a pipe extension 35, and the plate 29 has an oppositely disposed projection 36, for engagement by the rod of the jack 23, the jack being positioned on the channel plates 5, as shown in Fig. l. By the action of the jack a force is imparted to the plates 2S and 29 to twist the same back into a normal position, the operation being controlled somewhat and steadied by the bar 34, as in the former case. By tilting the blocks 32 and 33, as shown in Fig. 5 in dotted lines, they can be caused to engage the inclined ends of the axle, While the clamp-plates retain their horizontal position.

By means of the jack a sufficient amount of force may be applied to the axle to twist it Without heating it, and in that respect the invention comprises one of several sets of tools Which are designed for the correction of various faults in an axle Without first subjecting the axle to heat, and usually Without the necessity of removing the same from its place in the vehicle. Other devices of this group are set forth in the applications hereinbefore referred to.

While the invention has been set forth herein in its use in connection With an operators pit and cross-beam set therein, it is not limited thereto, but can be employed in any place Where a suitable support can be found for the angle-plate frames, such as a stationary rack above the ground, teeterrack, and the like. Changes can also be made in the form and arrangement of the parts of the invention aside from those set out herein, Without departing from the spirit of the invention. The angle-plates 6 and l0 can also be arranged for vertical adjustment of the latter plates, as set forth in said companion applications.

That- I claim and desire to secure by Letters Patent, is

l. A press for automobile axles, comprising a beam held rigidly in place, a jack mounted on said beam axle supporting frames fixed to said beam, means for holding an axle rigidly on said frames, and a bar engageable With one end of such axle, and provided With an extension for engagement by the rod of a jack positioned on said beam.

2. A press for automobile axles, comprising a stationary beam, frames supported thereby provided With axle supports, means for holding an axle tightly on said supports,

a bar provided with means for engagement with the sleeve on the end of an axle, provided with means for engagement with the rod of a jack, and means for controlling the action of said bar in operation.

3. A press for automobile axles, comprising a stationary beam, frames fixed to said beam and provided with axle supports, means for clamping an axle on said supports, a bar provided with a bearing, a pin connected With said bearing and adapted for insertion in a sleeve on the end of an axle supported on said frames to project beyond the same, a corrugated wedge insel-table between said bar and the end of said pin, a handle for said bar, and an expansion element interposed between the end of said bar and said beam.

In testimony whereof I atlix my signature.

HENRY VVOCHNER.
